Abstract

L'invention se rapporte à un système d'enregistrement vidéo numérique centralisé et de reproduction qui relie plusieurs unités de reproduction et de contrôle (telles que les récepteurs de télévision. Etc.) et un serveur centralisé au moyen d'un réseau domestique. Ce système permet de répartir la programmation dans tous les lieux et permet d'effectuer un nouvel enregistrement et une lecture à pause en directe à partir de plus d'une unité de reproduction et de contrôle sans coupure. Par exemple, au cours d'un épisode à pause en directe, un utilisateur peut arrêter un programme depuis une unité de contrôle et de reproduction sur les lieux. L'invention en question permet également à un utilisateur de visionner plusieurs programmes depuis le serveur sur le même écran au moyen d'un affichage à plusieurs insertions d'images.
